Normally, the program cycles through steps 81-85. At step 81, all the flags, counters, etc. in the microcomputer (4η) and the output of the microcomputer (4η) are reset, and the output of the microcomputer (4η) is reset.
2. At EI5.84 and B5 step, the operation section 111 is
Then, it is determined whether the grill key (4), oven key (5), fermentation key (6), and microwave key (7) are currently being operated.

[l] Then, microwave cooking is performed (2. First, place the food 1111 on the turntable (131),
Operate the microwave key (7:) using the operation unit (1) C2.

Then the program cycles through steps 81-85.
Step 6-Escape and take 86 steps! = reached, and it is determined whether or not the start key (8) is currently being operated.

In this case, such a key operation has been performed (H, o), and the program remains at step S6. After turning the timer knob (3) to the desired time scale, the start key (81) is operated.

Then the program will move from step 86 to step 87 (
Binary, timer counter TIMB in microcontroller (4?)
The above-mentioned processing time is set to
A one-second start starts in the ME. Continued <8
In step 8, it is determined whether the count of the timer TIME has reached 0 or not. In this case, it is the count content, and the count content is not 0,
Therefore, the program advances to step 89, in which the second drive circuit (mark 4) is driven and the blower motor 02 begins to rotate, and the cooling of the magnetro 7001 and the rotation of the turntable (1) are started.

Next, the program goes through 510-812 Sudekubu and goes to S1.
Proceed to step 5. That is, in steps 810-812, the flag FLA in the microcomputer (47) is set.

It is determined whether FLB and FLO have been 1c falsified, but in this case, none of the flags FLA, FLB, and PLO are set, so the program is executed as described above (S
Proceed to step 15. And in step S16, the 6th step,
The fourth drive circuit 161ζ (51) starts driving, and the fifth drive circuit 161ζ (51) starts driving.
The 9th race switch (Iω) is switched to the high voltage supply circuit Oa side and the fourth relay switch (16) is turned on.Therefore, the magnetron (II) is energized and microwave heating is started.

Thereafter, the program cycles through steps S8 to E115 unless the count of the timer TIME becomes zero. Then, when the count contents are QC, the program repeats the cycle from 88 to 815 steps by 88 steps (
: Remove and return to S1 step C2 to complete microwave cooking. After that, the program enters a circular state (:) of steps 81-85.

[■] Next C: When grilling, first place the two foods qυ on the turntable 03, and then press the operation part fi+(
: Operate the grill key (4). Then, the program exits the cycle of steps 81-85 at step 82 and reaches step 814 (; flag FLAi knee 1 is set, and the timer knob (3) is turned to the desired cooking time scale. Operate the rear start key (8;).

Then, the program similarly passes through steps C86 to S9 and reaches step C=810, but after that the flag FLA is set to 1.
Therefore, the process reaches step 815.

In this step, the 'iE4 drive circuit (51) is driven to start continuous energization of the heater i11, and therefore, in step 89, since the C nib blower motor (17J) has been rotated, hot air begins to be generated. Now for the second
It is determined whether or not the cam switch is on. If the switch C is currently off, the program advances through 817 steps and the first drive circuit (mark 4 is driven to start the cam motor. After that, the program cycles through steps 88-81Q and 1315-817, and when the second cam switch 1D (increase) is turned on, the hot air discharge direction is changed as shown in Figure 4B. Then, 8
The cycle of 8-810 degrees, 815-817 steps goes to step 816 (it exits and goes to step 818, in which the rotation of the cam motor C351 is stopped, and the rotation of the cam motor C351 is stopped, and the rotation of the cam motor C351 is stopped. Grilling is carried out by circulating hot air and blowing the hot air directly onto the food.

And the count content of timer makunta' IIMR is 0.
(At 2, the program returns to step S1 and C2, thus completing the grill cooking.) After that, the program enters a cycle of steps 81 to 85 (-).

(1) Next, when performing oven key processing, first place 1υ of food on turntable 03 (:
11: Operate the oven key (5). Then, the program cycles through steps 81 to 85 in 85 steps (=
The process exits and proceeds to step 819, where the flag FLB is set to 1. After turning the timer knob (31) to the desired cooking time scale and rotating the temperature knob (21) to the desired oven temperature scale, the start key (8) is operated.

Then, the program goes through steps 2B6 to S10 and reaches step C: 811 as in the case of microwave cooking, but after that, since the flag FLB is 1, it reaches step C: 820. In this step, in order to maintain the temperature inside the heating chamber (9) at the above-mentioned oven temperature C2, the supply of electricity to the heater port 9 is controlled based on whether the temperature detected by the thermistor (side) has reached the above-mentioned oven temperature. Wagyu beef control begins.

In the following step 821, the first cam switch C1? ) is on or not. Now, such a switch ff
, +7) are off, the program goes through steps 822, which are similar to steps 817, and then
20-822 steps are circulated, and when the first cam switch D is turned on, that is, the hot air discharge method is changed as shown in Fig. It circulates through steps 88 to 811, 820, 821, and 826 through similar steps 825. Therefore, under the above control (2), the generated hot air directly hits the side wall of the heating chamber (3) and 2) (C2). executed.

From then on, the content of the timer power wanta TIMIIC is D.
When C=, oven cooking is completed and the program is 81~
Cycle through 85 steps.

(IT) Now, when performing fermentation cooking, first place the turntable (13I (food adc figure 4) on which Nirakupu (1, 11L) has been made), and press the fermentation key (6) on the operation part L: Then, the program exits the cycle of steps 81-85 at step 84 and advances to step C2 of 824, where 1 is set in the flag PLO.
After turning the timer knob (3) to the desired time scale, operate the start key (8).

Then, the program will be 8 as in the case of microwave cooking.
The process goes through steps 6 to 811 to reach step 812, but since flags FI and O are 1, the process goes to step C2 of 825, which is similar to step 821.

At this time as well, assuming that the first cam switch (3η) is off, the program is
When the first cam switch C17) is turned on, that is, when the hot air discharge direction is changed as shown in Fig. 4, the circulation is repeated 825 steps. I: 818
and 823 steps and 827 steps similar to 823 steps.
Go forward 8 steps.

In this step, in order to maintain the temperature in the heating chamber (9) at a predetermined fermentation temperature, for example, 40°C, the heater (11 The energization control, that is, the hot air generation control is started.The hot air is then directly directed to the side wall of the heating chamber (3) based on the changed hot air discharge method, so that fermentation cooking is performed. .

After that, when the content of the timer TIM E becomes DC=, the fermentation cooking ends and the program starts from 81 to S.
Cycle through 5 steps.

Here, in the case of fermentation cooking, even if the hot air discharge direction is rotated as shown in Figure 4B, even if the hot air discharge direction is changed as shown in Figure 4A, even if C Nigrill cooking is performed before that, the hot air discharge direction is changed as shown in Figure 4A. Since the hot air is discharged from the
